I feel ashamed for saying I don't watch/read Game of Thrones...
I was thinking about getting into it... but Morrowind comes first, then Game of Thrones
Anyhow, Fadrill's temper is more similar to Vernon Roche when he is angry, but with Iorveth's direct threats added in, so I guess he's the best of both
Frankly, I don't like Game of Thrones, and I stopped watching after Sean Bean, who played Eddard, left the show.
For those who never watched Game of Thrones, or read A Song of Fire and Ice, I'd say he's what would happen if Faramir became Steward of Gondor.
Maybe Fadrill takes the worst from both?
He is as arrogant as Roche, and as violent as Iorveth.
